It was quite a rare treat last night as Britney Spears hit the red carpet in Beverly Hills with her beau Jason Trawick! We haven’t seen Brit out at an event in we don’t know how long, and she looked pleased to be co-hosting An Evening of “Southern Style” presented by the St. Bernard Project & the Spears family at a private residence last night. Stars like Selena Gomez, Kim Kardashian, Hilary Duff and Mike Comrie, Kelly Osbourne,Jessie J and Christina Milian all showed up in style.
